The Best of Show image from the 2018 Ocean Art Underwater Photo Competition was shot by Duncan Murrell in Honda Bay off the Philippines. It uses soft light to accentuate the swirling ballet of the three spinetail devil rays, as two males pursue a female. In addition to the best in show honor, Murrell won first place in the marine life category, and a cruise to Indonesia's southern islands.
PT Hirschfield won first place in the compact behavior category, and a seven-night dive package, for his image taken off Victoria, Australia. It shows a ravenous unmolted spider crab fiercely feasting upon a freshly molted crab.
Sejung Jang took first place in the compact macro category and won a seven-night cruise for this shot, taken in Anilao, Philippines. It was the Korean photographer's first time seeing red hairy shrimp.
Melody Chuang won first place in the compact wide-angle category for this shot of jellyfish off of Taiwan. Her husband, Stan Chen, used a flashlight to backlight his wife's photos as the couple followed the jellyfish for over a mile.
Jeff Milisen won first place in the macro category and a diving trip for this photo of a sharp-eared enope squid in Hawaii. He followed it to a depth of 90 feet before deciding "it was time to leave my new little friend at peace."
Fabrice Dudenhofer won first place in the mirrorless behavior category, and a seven-night trip to the Solomon Islands, for this shot of a clown fish and its eggs, taken in the waters off Japan. The photographer reported that the parents swam endlessly around the eggs in order to oxygenate them.
Bruno Van Saen took first place in the Underwater Art category and won a weeklong cruise for this shot dubbed "Disco Nudi," which uses a Photoshop filter to create a swirl around a nudibranch spotted in Bali, Indonesia.
